55 Claims. (Cl. 12-12.3)

The present invention relates to shoe upper shaping mechanism and is a division of United States Letters Patent No. 2,740,138, granted April 3, 1956, on an application tiled in my name. The invention is herein illustrated in its application to machines for lasting the heel -end portions of shoe uppers but it is to be understood that the invention is not limited to heel end lasting machines, the invention in certain aspects thereof being applicable to lasting machines generally.

It is an object of the present invention to provide shoe upper shaping mechanism which will cooperate with other mechanisms disclosed iny my Patent No. 2,740,138 above referred to, to prepare the rear portions of shoes for operations subsequent to the operation of the machine illustrated in my patent No. 2,740,138 so that the breast line portions of the shoe upper materials, particularly vthe marginal materials at the edge of the shoe bottom,

are located with precision and uniformity to the end that 'the shoe bottom materials at opposite sides of the breast line portion of a given shoe are exactly alike as to their `disposition on the last,y and further to the end that the breast line portion of each shoe will duplicate exactly the breast line portion of every other shoe on the rack as to the disposition of the shoe materials on the last.

Such preparation of the rear parts of shoes opens a iield for certain types of automatic machines which heretofore have not been commercially useful because there has been no commercially practicable way of preparing the Work for the operation of such automatic machines. Machines of this type include automatic side lasting ma- ;chines such as that disclosed in United States Letters Patent No. 2,201,866, granted May 21, 1940, on an apmatic sewing machine of this ltype is disclosed in United "States Letters Patent No. 2,359,662, granted October 3,

1944, on an application tiled in the name of A. R. Mor- ,rill.

With the above and other objects in view, as will here- 'inafter appear, the present invention in one aspect thereof comprises a shoe upper lasting organization consisting of a pair of end embracingV lasting wipers which, in the illustrated machine, operate on the heel end of the shoe, a pair of carriers in which the lasting wipers are mounted, means herein illustrated as a` power operated cam mechanism for actuating the carriers rst to move the wipers into contiguous relation to each other and then to effect relative angular movement of the wipers in order to cause the wipers to wipe the lasting margin at one end of a shoe in the machine in over an insole on a last bottom. In the illustrated organization the wipers are constructed and arranged for separable articulation at their common axis of angular movement by the provision of a lateral projection of one wiper which operates in a complemenillustrated and described in my patent No. 2,740,138 above referred to, such other instrumentalities including grippers for tensioning the heel end portion of a shoe upper over a last. The lasting wipers arersupportedon two members which are mounted for angular movement on posts arranged at opposite sides of the machine and the angular movement of said members is employed'n connection with angular overwipiug movements of'the wipers. To this end said members carry rolls'constructed and arrangedto operate against cam surfacesV formed in the wipers respectively. In order -to hold the wipers in articulated relation to each other during the Wipingoperation means herein illustratedy as a latch isprovided for positively holding the wiper carriers against relative movement away from each other. After the completion of the wiping operation the latch is automatically released to permit the carriers to move the wipers away from each other and out of their mutually articulated position.l The movement of the wipers into articulated position is effected by means herein illustrated as a cam which imparts angular movement' to the members which support the wiper carriers. Means herein illustrated as a second cam imparts further angular movement vto said members in the performance of the-wiping operation. Means herein illustrated as a third cam advances the wipers toewardly relatively to the supportingmembers to overwipe the back line portion ofithe upper. 'Upon the completion of the wiping operations means herein' illustrated as a fourth cam retracts the wipers relatively to the supporting members and thereafter the members are swung about the posts on which they are mounted to return the wiper assemblies to their restpositions.

In an alternative construction ofthe :Wiper operating mechanism the latch for Vholding the'wipersin their articulated position is omittedandythe wipers are heldv against separation by connections between'the wiperl supporting members and the wipers, said connections in the illustrated organization including a rollcarried by each of the supporting members and arranged to act against the Wiper. In order to cause the Wipers to register ac'- curately with each other inV their articulated position means is provided for adjusting the rolls carried bythe wiper supporting members Vthereby to vary the positions of the wipers relatively to each other widthwise of the shoe. r

In order to facilitate the removal of a wiper from its supporting member and the substitution therefor of another wiper of a different size or style, the wiper actuating roll mounted in the supporting member `is pivotally mounted on a pin which isA constructed andiarranged to be removed from the supporting member in order to permit the wiper and the roll to be removed frornfthe supporting member. Before inserting another -Wiperj into the supporting member the roll istmounted in a slot provided therefor in such other Wiper and is advanced into the supporting member along with the Wiper." In order to provide for the adjustment of the lasting wipers for operation on different sizes of shoes within the range of sizes, for which the wiper i's constructed,v two xactuators herein illustrated as cams, are provided foradvancing the wipers. The first cam imparts an invariable wiping movement to the wiper and the second cam operates after the completion of the advancement of the wiper by the i'lrst cam to impart a variable wiping movement thereto. In the illustrated organization the second cam engages a roll carried by a slide which Ais adjustableY to move the roll toward and from the cam. The slide .is adjusted by the manual operationl of a screw which rotates in the slide and is suitably held against bodily movement.

In the heel end lasting operation ,the heelend Wipers gather the fullness in the lasting margin and lay it in pleats on the insole. In order to insure thelocation of the pleats in positions in which they will be secured by the lasting tacks the present invention contemplates .the formation in the lasting margins of the wipers of a plurality of grooves extending inwardly from the wiping edge in alinement with the apertures through which the tacksare driven, each groove terminating between the wiping edge and the adjacent aperture in order to permit thevpleat formed in the groove to be ironed out ilat beneath the aperture through which the tack is driven.

These and other features of the invention will now be describedrwith reference to the laccompanying drawings and pointed out in the appended claims.

As illustrated in the drawings, the present invention is embodied in a machine of the type shown, for example, in my P'atent'No; 2,740,138 hereinbefore referred to. Machines of this type are provided with means for supporting a lined shoe upper in inverted position by XXI1-XXn of engagement with its back'line portion, automatic means for inserting a moldedcounter into the heel end lportionrvof a supported upper, means for bringing the quarter lining into intimate contact with a counter positioned in the upper, and gripper mechanism for tensioning the breast line portion of the upper upwardly, toewardly and inwardly over an insole on the bottom of a last which is inserted into the supported upper after the lining is brought into contact with the counter. Suitable heel pads are provided for clamping the heel end portion of the upper against the last in order to maintain the tension imparted to the upper by the breast line grippers and thus to hold the heel portion of the upper in position for the operation of mechanism hereinafter-` described for performing a lasting operation thereon.

For wiping the lasting margin at the heel end portion of the upper inwardly over an insole on `the lastfbottom the illustrated machine is provided with a pair of wipers 30 and 32 (Figs. 15 and 16). These wipers swing or hinge on a common center adjacent to the back line of the upperto overwipe the lasting margin atopposite sides of the heel portion of the upper and advance bodily toewardly to overwipe the lasting margin at the rextreme heel end of the upper. To provide for mutual articulation of the wipers at the hinging point the wiper 32 has a lateral projection 34 extending to the left as seen in Fig. 16 for engagement in a complementally Vshaped recess inthe left wiper 30.` The lateralprojection 34 is characterized by an arcuate edge face which is slightly less than semi-circular in extent and therefore is separable from the complementally shaped recess in the left wiper 30. The lateral projection 34 is so constructed and arranged that the meeting edges of the wipers at the point of articulation are centrally spaced between the adjacent tack holes in the margins of the wipers. f It will be understood that the center of curvature of the 'projection 34 is the common axis on which the wipers swing. The center,k of said projection is also the common center of two arcuate tongues 36 extending upwardly from therear end portions'of the wiper plates for sliding engagementl in arcuate grooves formed in a pair of wiper carriers or plates 38 arranged in contiguous relation to the top surfaces of the vwiper plates.v Referring to Fig. 2, the grooved plates and the wiper plates are confined between top plates 40 and base plates 42comprising two wiper supporting assemblies freely mounted for angular movement on posts 44 (Fig. l) mounted in and extending upwardly from a table 45. The right wiper supportingv assembly is held against downward movement by Aa thrust bearing 46 (Fig. 2) mounted von the post 44 and sup-A ported by a collar 48 xed to the post, and the left wiper supporting member is similarly upheld. The plates38 overlie the greater part of the area of the wiper plates and prevent any vertical play between the wiper plates and the plates 40 and 42. At their outer margins the plates 40 and 42 are secured to spacer membersrtlhaving a thickness corresponding substantially toV the combined thickness of the grooved plates and the wiper plates. i In the operation of the machine the plates 40 and 42'are swung inwardly as a unit toV actuate mechanism for effecting the mutual closing movements of the wipers, and the grooved plates 38 are moved toewardly thereby to advance the wipers bodily to perform the overwiping operation'at the extremity of the heel portion of the shoe. Referring to Fig. 15, the mechanism for imparting closing movement to the wiper plate at the right side of the machine comprises a roll 52 vcarried by the base plate 42 and arranged to operate in an angular slot formed in the wiper plate and having a relatively long section 54 extending generally Vlengthwise: of the shoe in the machine and a relatively short section 56 extending widthwiseof the shoe with a toeward inclination. When the machine is in its rest position, as shown in Fig. l, the wiper plates are separated from each other widthwise of the machine in order to provide clearance for the operations of instrumeritalities including the back line wiper vmechanism, and the roll`52 '(Fig. `l5) is located adjacent to the end of the short portion 5,6, 0f i116 slot. Iny ther operation of the wiper mechanism the plates 40 and 42 are swung in- WardlyiirsttoV bring the wiper plates into their articulated position shown in Fig. 15 and then to close the wiper plates into their overwiped position shown in Fig. 16. During the movement of the wipers into their articulated position relative movement of the wiper plate and the roll 52 positions the roll at the apex of the angle defined by the twofsections 54 and 56 of the slot. During the closing movement of the wipers the roll moves relatively to-the long portion 54 of the slot into its position shown in Fig.- 16. `This position of theV roll relatively to the slot will vary with diiferences in the degree of closing movement and toeward movement' of the wipers. Referring to Figl, the groovedplate 38 at the right side of the machine has a rearwardly extending shank portion 58 secured toa slide 60 mounted in a guideway in a carrier 62, the forward'portion of which has an open ended slot 64 whichY provides clearance for the movements of the shank portion 58 of said plate 38. The grooved plate at'the left side of the machine is mounted on a slide'66 similar tothe slide 60 and the slide 66 is mountedA in a carrier 68 similar to the carrier 62. In order to effect bodily toewardmovement of the wipers the slides 60 and 66 are advancedconcomitantly by mechanism hereinafter described. Referring to Pig. 7 the slidel 60 has a relatively Wide'forward portion in which there is formed an arcuate concave abutment surface 70 constructed and arranged to engage the arcuate convex rear surface of the tongued portion 36 of the wiper plate. Also formed in the slide 60`is an arcuate concave abutment surface 72 constructed and arranged to engage a complementally shaped'edgeV face of the wiper plate Voffset rearwardly and outwardly from the tongued portion of the wiper. Said abutment surfaces are concentric to the common center of closing movement of the wiper plates. The retracted position of the wiper plate at the right side of the machine,'shown in Fig. 7, is determined by the engagement of its rear edge face with the forward end of an abutment screw 74 mounted in a tapped hole in a lateral extension ofthe forward portion of the slide 60. In order to lcause the plates 38 to register accurately with each other when thev Wipers areb'rought intohingng position the plate at the left side ofthe machine is provided with an ear 76 (Fig. 8) having a semicircular edge face andthe plate at the right'side of the machine is provided with a recess having'a shape complemental'to said ear and arranged to receivethe'ear when the wiper assemblies are advanced into their'hin'ging position shown'in Fig. 8.

In order to facilitate the removal of either wiper from the machine for repair or replacement the roll 52 is mounte'vd'on the reduced upper end portion of a headed screw 78 (Fig. 9) mounted in a tapped hole in the base plate'42.` The head of the screw engages the bottom of the base'plate and is positioned near the forward end thereof and'readily accessible by the operator. When it is desired to remove either wiper from the machine the screw'78is removed from the base plate 42 and the wiper plate, together with the roll 52, are slid forwardly between the base plate 42 and the overlying plate 38. As shown in Fig. 8, the arcuate grooves 80 in the plates 38'are extended to the inner edge faces of the plates, respectively, to permit the tongues in the wipers to move freely Vout 4of'said grooves. Preferably the machine is in its rest'position with the roll at the forward end of the short portion of the slot in the wiper plate, asshown in Fig. 7, when the wiper is removed from the machine. In mounting said wiper or a replacement therefor in the machine the rOll is located -at the forward end of the slot `as shown in Fig. 7, and the wiper is advanced between its supporting plates with the roll in this position until it is located in correct relation to saidlplates. The roll may then be accurately positioned to receive the screw 78 byl means of a blunt pointed tool inserted throughthe tapped hole inthe base plate.

In Fig. 10 there is illustrated an alternative Wiper assembly which differs from the assembly above described in the construction of the top platel and av plate lying between it and the wiper and identified by the numeral 82. There are also minor modications in the construction of the wiper plates. The plate 82 is provided with an angular slot 84 in which is mounted a roll 86 which extends upwardly from said slot into a short rectilinear slot 88 in a top plate 90 corresponding generally to the top plate 40 above described. The roll 86 is mounted on a pin 92 mounted in and projecting downwardly from the left end portion of an arm 94. Fixed in and projecting from the right end of said arm is a threaded rod 96 which extends freely through a bore in a lug 98 projecting upwardly from the top plate 90. Two lock nuts on the threaded rod secure the arm 94 in predetermined relation to the lug and hold the roll 86 against movement longitudinally of the slot 88. The slot' S8 extends generally widthwise of the machine, its angular disposition being such that it never comes into a position in which its side walls are coplanar to the side walls of the slot 84. When it is desired to vary the degree of the overwiping movement of the wipers at the extreme heel end of the shoe the lock nuts 100 are released to permit a slight movement of the roll 86 through the slot 88 whereupon the plate 82 is manually adjusted forwardlyV or rearwardly as required. Preferably this adjustment is made after the machine has come to rest at the end of the second third of the machine cycle. At this time the wipers have moved inwardly into their articulatedposition and are ready for the overwiping operation which occurs at an early stage in the last third ofthe main cycle. If, after making the above adjustment the wiper plates are slightly separated from eachotherat the point of articulation the varm 94 and the corresponding arm at the left side of the machine are moved toward each other in order to bring the wiper plates into articulated position. The lock nuts 100 are then tightened against the lug 98 in order to secure the arm 94 in adjusted position, and the corresponding arm at the left side of the machine is similarly secured. The rear portion 102 of the slot 84 is made concentric to the post 44 in order that the roll 86 and the companion rollin the left wiper assembly (not shown) may serve to hold the Wipers in articulated position while they advance to wipe the lasting margins of the upper and the lining inwardly over an insole on the last bottom.

In the operation vof the machine the roll v86 moves from the forward endof the slot to the rear end thereof. During the movement of the wipers into articulatedposition the roll and the slot move relatively to each other to cause the roll to be positioned at the bend of the slot at the same time a roll 104 in an angular slot 106 in a wiper plate 108 is positioned at the bend in its slot. During the closing movement of the wiper plates the rolls move relatively to their slots until they come to rest in their respective positions shown in Fig. 10. In place of the tongue 36 and groove 80 in thewiper assembly illustrated in Figs. 7 and 8 the plate 82 illustrated in Fig. 10 is provided with an arcuate slot '110 having its center of curvature at the axis on whichthe wiper plate swings and a pin 112'is mounted in the arranged to project upwardly therefromv through said slot. In order to cause the wiper plate 108 to register accurately with'its companion wiper plate (not shown) when said plates `comeinto their articulated position, the illustrated wiper plate is provided with a pointed ear 114 which is reduced in thickness by cutting away its top portion as far as a shoulder 116. The rear edge face of the ear isin the form of an arc concentric to the slot and its forward edge face is bilaterally symmetrical to the shoulder 116. A similar ear formed in the com` panion wiper plate overrides the ear 1'14 and comes to rest with its leading edge face in yabutting relation to the shoulder 116 and its rear edge to the arcuate face 70 of the slide 60.

face in abutting relation` 7 Referring to Fig. 11, 'the rear vportions of the carriers 62 and 68 have secured to their bottom faces arms 118 and 120, respectively, arranged to extend inwardly therefrom and forming at their inner ends a halved joint (Fig. 13) through which extends a headed pin 122 the threaded lower portion of which is mounted in a tapped hole in a fixed horizontal plate 124; For advancing the slides 60 and 66 forwardly to cause the wiper plates to wipe the lasting margin at the extreme heel end of the shoe inwardly and toewardly over an insole on the last bottom a cam 126 (Fig. 14) is fixed to a vertical cam shaft 128 and arranged to engage a roll 130 carried by an angle arm 132 secured by two screws 134-to the rear portion of the slide 60, said-roll being positioned centrally between the rear ends of the two slides. The arm 132 is slotted to receive the screws 134 and is'adjustable longitudinally of the slide 60 in order to vary the extent of the forward movement of the slides and therefore the degree of toeward overwiping movement -of the Vwiper plates.- The slide 66 moves forwardlyV concomitantly with the slide 60 by reason of the engagement of the roll 130 withthe laterally extending portion of an angle arm 136 fixed to the slide 66 and adjustable thereon in the same manner as the arm 132. The anglearms 132 and 136'are oriented by the engagement of their opposite side faces with the side walls of open ended slots 138 formed in the carriers 62 and 68,

respectively. For moving the slides 60 and 66 rearwardly into their rest positions a cam member or arm 140 (Fig, l) is xed to the vertical cam shaft 128, said arm having secured to its bottom surface a cam plate 142 the rear edge face of which is arranged to engage the roll 130. The cam plate is mounted for angular adjustment on a fulcrum 144 and is secured in adjusted position by a clamping screw 146 extending downwardly through a slot in the arm'140 and into a tapped hole in the free end portion of the cam plate. In order to cause the slide 66 to move rearwardly concomitantly with the slide 60 an angular arm 148 is fixed to the slide 60 by the screws 134. The laterally extending portion of said arm 148 has an ear 150 (Figs. l2 and 14) projecting rearwardly from its end portion and located centrally between the slides. Said ear engages an arcuate concavity formed in the arm 136 during the rearward movement of the slide 60. For preventing excessive rearward movement of the slides 60 and 66 manually when the machine is at rest abutment screws 152 (Fig. 11) are mounted in plates 154 ixed to the rear ends of the carriers 62 and 68, respectively, and arranged to abut the rear end faces of the slides, respectively.

For impartingr closing movements to the wiper plates in order to wipe the lasting margins at opposite sides of the heel portion of the shoe inwardly widthwise of the shoe over an insole on the last bottom the illustrated machine isprovided with two cams 156V (Fig. 4) and 158 (Fig. l) both fixed to the vertical cam shaft 128. The cam 156 imparts a predetermined and invariable closing movement to the wiper plates and the cam 158 supplements the action of the cam 156 and imparts tothe wiper plates the latter part of their closing movements the extent of which is Variable by the'a'djustment of mechanism hereinafter described. The cam 156 acts against a roll 160 (Fig. 6) carried by a slide 162 mounted on a platform 164 and guided by gibs 1'68(Fig. 4) fixed to the platform, the slide 162 being centrally 'positioned widthwise V of the machine. The slide is provided with a longitudinal-slot 170 to provide clearance for the cam shaft 128, said slot being long enough to provide for the operating movement of the slide. At its forward end the slide has xed thereto a crosshead 172 to the opposite ends of which are pivoted two'links 174. At its forward end each link is longitudinally grooved to receive anoutwardly bent arm 176 (Fig. 15) which is secured thereto by clamping screws 178. At its forward end the arm 176 is pivotally mounted on a headed screw 180 projecting downwardly from the base plate 42. It will be seen that rearward movement meshes with a spur gear 310 fixed to the hub ofka clutch,

. 8 of the links 174 bythe successive operations` of the cams 156 and 158 causes the wiper carrying plates toswing inwardly on the posts 44 thereby to impart closing movements to the wiper plates. Referring to Fig. 6, the cam 158 operates against a roll 182 pivotally mounted on a headed pin 184 projecting downwardly from the upwardly offset forward portion 186 of a slide 188 mounted on the upper surface of the slide 162 and guided theref on by gibs 190 fixed to the slide 162 and having anges positioned in longitudinal grooves extending inwardly from the opposite side faces of the slide 188. In Order to adjust the roll 182 toward or from the cam 158 in accordance with the width of the shoe to be operated upon the slide 188 is adjusted by the operation of a shaft 1.92 journaled in a bearing in a boss 194 formed in and projecting upwardly from the` rear portion of the slide 162. The forward portion of the shaft is threaded for operating engagement in a tapped hole in a lug 196 projecting upwardly from the slide 188. The shaft is held against endwise movement relatively to the boss 194 by a pinion 198 fixed to the rear portion of said shaft and a ange,200 formed on the shaft and arranged to engage the front face of the boss. The machine is providedwith manually operated mechanism hereinafter described forV rotating the shaft 192 in order to adjust the'roll V182 toward and from the cam 158. A hand lever (not shown) is provided for. rotating the shaft 192 inl order to adjust the roll 182 toward and from'the cam 158. The hand lever rotates a,

shaft 298 (Fig. 1) which has xed thereto a bevel gear 3410 arranged to mesh with a bevel gear 302 fixed to a shaft 304 mounted in a bearing in'afixed bracketp306. Also tixed to the shaft 304 is a spur gear 1308'which member or disk 312 mounted to rotate freely in a bore in the cylindrical head 314 of a bracket 316 fixed to the machine table 45. The diskl and the gear mounted thereon are held against movement endwise of the head 314 by a collar 320 fixed to the hub of the disk. Referring to Fig. 3, the disk 312 has formed therein a marginal ange 1n which are vmounted a plurality of pins 322 constructed and arranged to be received in corresponding bores formed in the marginal ange of a clutch member o r diskl 324 fixed to a shaft 326 mounted for rotary and sliding movements in the hub of the disk 312 and in a bearing formed in a bracket. 328 fixed to the table 45V. The disk 324 is normally urged forwardly into engagementwith the disk 312 by a spring 330 surrounding therearportion of the shaft 326 andV confined between the bracket'328 and a collar 332 fixed to the shaft.

with a rst idler 336 freely mounted on a headed screw 338 1n a fixed plate 340. The idler 336 meshes with a second idler 342 freely mounted on a headed screw344` (Fig. 3) in the plate 340. The idler 342 meshes with a spur gear 346 xed to a shaft 348. Said shaft is mounted the hand lever operates through the connections above described to cause the screw shaft 192 to adjust the cam roll 1.82 (Fig. 6) toward or from the cam 158.

During the overwiping `operation the Wiper plates arey positively held in contiguous relation to each other; at the I pivoting point. When the machine is equipped with the.

wiper assemblies illustrated in Fig. 8 the wiper plates are held against separation by mechanism now to be described. When the machine is equipped with wiper'assemblies of the type illustrated in Fig. l0 the wiper plates are positively held against separation at the pivoting point Fixed to the rear end of, the shaft 326 1s a spur gear 334 (Fig. 5) which meshes,

by the engagement of the roll 86 with the inner wall of the rear'portion 102` of the slot 84. In Figs. 2 and 17 there is illustrated mechanism for holding against separation the wiperplates 30 and-32 illustrated in Fig. 8. This mechanism comprises a latch arm 202 fixed to the bottom of the'carrier 62 and a detent 204 pivotally mounted at 205 ona' plate 206 tixedvto the carrier 68. A leaf spring 208 fixed to the top of the carrierV 68'normally holds the detent in its position shown in Fig. 17, said positiony being determined-by the'engagement o'f the tail portion 210 of the detent with the bottom of the slide 66. Referring to Fig.'8, the latching position of the mechanism above describedis determined by the engagement of abutment screws 212 xed'in brackets 214 mounted on the carriers 62 and 68, respectively, with the outer surfaces of rails 216 and 218. After the completion of the lasting operation the detent 204'(Fig. 17) is moved upwardly out of engagement with the latch-ann toV permit the wiper assembliesto move awayffrom `each other into their respective rest positions, as shown in'Fig. l. Tothis end a cam 220 (Fig. 17) is fixed to a horizontal cam shaft 222 and arranged to'engage a'roll 224 mounted inr thefree end portion of an arm 225, said arm being provided with downwardly extending ears 226 `which engage opposite sidesof the cam to maintain registration ofthe roll therewith'. The cam imparts upward movement to a vertical slidingro'd 228and aslide 230. At its upper end the slide- 230 has an inturned porn'on 232 arranged to engage a pin 234 projecting rearwardly from the detent 204. Said inturned end portion holds'the detent out of engagement withthelatch arm'until the wiper assemblies begin their movementof separation. At an early stage in the movement ofl separationof thewiper assemblies the pin moves away'from saidinturned end portion and the spring 208 returns the 'detent to its position shown in Fig. 17.

Concomitantly with the openingmovement of the wipers afterthe completion of the heel end lasting operation the wiper supporting'members between which the wiper assemblies are mounted are swung outwardly to moveV the wipers widthwise ofthe machine out of their articulated position and into their respective retracted positions. In

the illustrated machine the outward movement ofv said platesis effected by the operationV of an arm 236 (Figs. 4 and 5) fixed to the vertical cam shaft 128 and positioned beneath the platform 164. The' arm carries a rol1'238 which engages a cam face 240 at'the free end of an arm 242 pivotally mounted on a headed screw 244'proj'ecting downwardlyA from the platform. The arm 242 has an arcuate extension 246 projecting laterally therefrom and arranged to engage airoll 248 (Fig. 6) pivotally mounted at the forward end of an arm 250 xed to and-extending forwardly from `the rear portion ofthe slide 162 and spaced vertically therefrom by a plate'252. In the operation of the machineV the vertical cam shaft 128 rotates in a clockwise direction, as seen in Fig. 4, causing the roll 238 to engage the cam Yface240 thereby swinging the arm 242 in a counterclockwise direction, thus causing the concave surface of the Iarcuate extension 246 of said arm to engage the roll 248 and move the slide 162 forwardly, or to the left as seen invFig. 4. Referring to Fig. 1, the forward movement of the slide causes the links 174 to impart clockwise movementto the plates 40 and 42 at the left side of the machine and counterclockwise movement to the corresponding plates'at the right side o'f the machine. In order to cause the wipers to swing outwardly relatively to the 'plates into their respective'retracted positions each wiper is urged outwardly by a spring 254 the rear portion of which is anchoredto a screw eye in a post 256 and the forward portion of which is connected to a chain 258 which extends forwardly around a grooved pulley 260 carried by an angle plate 262 fixed to theV plate 40 and is anchored at its forward vend to a pin 264 (Fig. 7) mounted in the forward portion of the wiper plate.

Upon the completion of the overwiping movements of the wipers the overlasted margin of the heel portion of 10 the upper together with therange of the counter and the inwardly extending bottom margin ofVY the lining are permanently secured to the insole on the` lastbottornby fastenings herein illustrated as tacks -driven through suitable apertures in the wipers by mechanism hereinafter' described. Referring to Fig. 16, a central tack is Td'ri'ven through an aperture 266 in the wiper 32 located incon# centric relation to the common axis on which the wipers close Similar apertures are providedV in the marginsof the lasting wipers 30 and 32 andare arranged, as .shown in Fig. 16, to extend from the central aperture-266 to the forward ends of the wipers. Referring to Fig'. 20, each aperture registers with a vertical bore 268 formed in a block 270 extending upwardly from the wiper plate'. A tack is driven through each aperture and into the shoe by a'driving pin 272 extending downwardly'from a driving head 274 into the bore 268. A tack such,fr example, as the tack 276 illustrated'in Fig.v 23 is`condi1cted into the bore 268 through a flexible tack tube 278 the lower end portion of which is mounted in a counte'rbore in the Ablock 270 and registers with anangular bore 280 which forms a junction with the bore 268. The tack comes to rest in a pocket 282 formed inV a horizontal slide block 284 which moves to the right against the pressure of a spring 286 (Fig. 20) when the pin moves downwardly to drive the tack. It sometimes happens that one or more tacks are jammed in the tack pocket and must be removed from the pocket before the operation of the machine is resumed. In order to facilitate the removal of such tacks from the pocket the illustrated block 270 is provided with a removable cover plate l288 the inner surface of which forms one wall of the tack receiving pocket. The upper portion of the cover plate is inwardly offset from its lower portion and mounted in a rabbet formed in the block. Referring to Fig. 22, the illustrated cover plate is coterminous with the lower portion of the inner surface of the block 270 and is concavo-convex as seen in plan view. The cover plate is secured to theblock 270 by a headed screw 290 (Figs. 20 and 2l) extending through a countersunkhole in the cover plate and into a tapped hole inthe block. The rear end of the cover platev is located by a pin 292 projecting laterally from the block into an open ended slotinl the cover plate.

The action of the'lasting wipers on the overlasting To this end the inner margin of each wiper plate is pro-k vided with grooves, identified in Fig. 19 by the numeral 294. The grooves receive the marginal materials during the advancement of the wipers and cause the pleats'to `be formed and positioned beneath the apertures through which the tacks are driven. It will be seen that there is a groove adjacent to each aperture, the side walls of'each' groove extending divergently from the aperture to the edge of the'wiper. As shown in Fig. 23 the depth of the groove decreases progressively from the edge face of the wiper plate to a terminating point adjacent to the aperture.

In the operation of the illustrated machine the wiper assemblies illustrated in Fig. 1 remain outwardly oiset from each other' during the greater part of the machine cycle while operations preliminary to the heel end lasting operations are performed by mechanism illustrated and described in my patent No. 2,740,138 hereinbefore referred to. These operations include the actuation of feather line pads 296 (Fig. l) to clamp the heel end portions of the shoe upper materials against the' last paratory to the heel end lasting operation.

After the operation of the feather line pads the cam 156 (Figs. 1 and 6) operates to swing-the heel-end wiper assemblies inwardly toward each other into'their articupre- - 1 1 lated position shown inFig. 8. As the wipers come into their articulated position-,the detent 204 (Fig. 17) engages the latch arm 202 to hold the wipers against movement out of their articulated position during their overwiping movement. Further operation of the cam 156 after the wipers have been brought into their articulated position imparts relative angular movement to the wipers and upon the completion of the operation of the cam 156 such relative angular movement of the Wipers is continued and completed by the cam 158 (Fig. 6) to cause the wipers to wipe the lasting margins of the upper and the lining at opposite sides of the heel end of the shoe inwardly over the insole on the last bottom. The degree of wiping movement of the wipers by the cam 158 is determined by the adjustment of the slide 188 (Fig. 6) which determines the position of the roll 182 relatively to the cam 158. Concomitantly, with the operation of the lcam 158 the cam 126 advances the wipers bodily toewardly in order to wipe the lasting marginsof the upper and the lining at the Iback line portion of the shoe inwardly over the insole. Upon the completion of the overlapping movement of the wipers mechanism (not shown) operates the tack drivers to drive lasting tacks through the overwiped upper materials and the. insole, clenching the tacks against the foot facing surface of the insole. After the tacks have been driven the cam 220 V(Fig. 17) operates to disengage the detent 204 from the latch arm 202 to permit movement of the Wiper assemblies away from each other out of their articulated position. Immediately after the detent is released the cam 140 (Fig. 1) retracts the heel end wiper assemblies rearwardly and theroll 238 (Fig. 4) on the arm 236 operates the lever 242 to return the wiper assemblies to theirrest position shown in Fig. 1.

If the heel Vend lasting performed by the illustrated machine is preliminary to a second heel end lasting operation which completes the shaping of the heel end portion of Vthe upper, only seven tacks are driven by the illustrated machine, three at the back line and two at opposite sides of the breast line portion of the upper. If, on the other hand, the lasting operation performed by the illustrated machine is the only lasting operation onthe heel end portion of the upper the illustrated machine drives tacks at regular intervals through the overlasted materials and the margin of the insole to secure the entire heel end portion kof the upper to the insole.
